Ctcf and cellular heterogeneity
Web1 day ago · It has been suggested that CTCF could bind more persistently CTCF-binding sites (CBSs) preferentially located at loop boundaries and co-bound by cohesin. 99 Also, CTCF contains RNA-binding regions that were shown essential for CTCF binding to chromatin and loop formation. 100, 101 These regions have been later linked to its … WebCTCF-occupied boundary elements even in the absence of direct physical interaction between boundaries, such as those mediated by CTCF-CTCF contacts (Fudenberg et al., 2016). Third, CTCF directly associates with cohesin, with a defined interface between the CTCF N terminus and the SA2 subunit of the cohesin complex (Li et al., 2024). The N ...

WebSmits et al. report that TLX3 chromosomal translocations in T cell acute lymphoblastic leukemia patients recurrently include intervening CTCF-binding sites in the breakpoint area. Pressure to acquire inactivating aberrations in CTCF abrogate consequential enhancer insulation that promotes TLX3 promoter to BCL11B enhancer looping boosts higher … DNA methylation can block CTCF binding in genome [34, 59,60,61]. The H19 imprinted control region (ICR) is an enhancer-blocking element required for imprinting of the H19 and Igf2 genes [62]. The conserved CTCF sites in HS1 and HS2 of the ICR are essential for the enhancer-blocking activity.
